Abstract
An output circuit for semiconductor integrated circuit includes an input terminal, an output terminal, a supply terminal, first and second transistors, and first and second drive circuits. One terminal of the first and second transistors are coupled to the power voltage terminal, and the other terminals thereof are coupled to the output terminal. The first drive circuit turns on the first transistor when voltage of the input terminal is in a different logical level from voltage of the supply terminal. The second drive circuit turns on the second transistor when voltage of the input terminal is in a different logical level from the voltage of the supply terminal, and turns off the second transistor when voltage of the output terminal is in the range between a predetermined threshold voltage and the voltage of the supply terminal.
